Hi

I'm only getting around 90 minutes from my 4 cell when just browsing the web (using Wifi) and doing a little word processing. When on battery all power setting are set to low via the Power Manager.

90 minutes is a long way short of the claimed 3 hours you're supposed to get. Is it the WiFi that's chewing the battery so quickly? I have the Inel ABG card. Anything else I can do to try improve my battery life?

What's eveyone else getting from their 4 cells?

My battery details are:
Design cap: 28.8
Full Charge cap: 24.97
Cycles: 25
First used: 06/2006

I never got 2h with wi-fi on just surfing. Max i got was 3h with screen pretty much dimmed to almost max.

What are your power settings (for the computer generally, and for the wifi card, in particular)?

My battery power setting are as follows:

Max CPU speed: Lowest
Optimize fan control: Balace all parameters
Display brightness: Level 1
Turn off display: after 5 mins
Stop HDD rotation: After 3 mins
Enter system standby: After 10 mins
Enter system hibernate: After 15mins

WiFi settings as set in Access Connections.
Wifi transmit power level set to 100%
Power save mode set to medium. My signal strength is not great at around 40% so I can't set this to High.

Enable radio management support is unchecked. I don't know what this does anyway.

It's the Slim 4 cell for X60s correct? Most people are getting around 2 hours from it.

Yep, that's correct. Is that 2 hours from full charge to run flat? I tend not to let me battery drop below 25% in the interest of preserving the battery. However, by the time it's got to 30% the power starts dropping fairly quickly so the last 25% can't offer more than 20-25 mins.
